Multiple times in a game I just played, it was impossible to defensively eat a friendly yi. I'm not sure the exact interaction, whether it's a pre-alpha strike targeting or if it's a meditation thing. Apologies that I can't be more specific.
You can't eat someone recalling, know that for sure. Not sure of how exactly it interacts with Meditate.
There are a lot of bugs with Tahm Kench right now. There's also one with his ult where sometimes when he uses it the camera will lock onto him indefinitely. Unfortunately, there are very few Rioters who peruse the "Report A Bug" section which leads to these bugs building up overtime and lasting longer than they probably should (camera lock bug has been in the game since last March).
